nRF24LE1 Preliminary Product Specification
nRF24LE1 includes a general purpose ADC with up to 14 input channels, depending on package variant.
The ADC contains an internal 1.2V reference, but can also be used with external reference or full scale
range equal to VDD. It can be operated in a single step mode with sampling under software control, or a
continuous conversion mode with a programmable sampling rate.

21.3.1
A write operation to the ADCCON1 register automatically starts a conversion, provided that the pwrup bit is
set. If the ADC is busy, the unfinished conversion is aborted and a new one initiated. Write operations to
ADCCON2 and ADCCON3 do not start a conversion. It is not advisable to change these registers while the
ADC is busy.
